McDonald's Meadowdale

McDonald's Meadowdale, Worst service ever. Got there, waited nobody at the desk. When they finally arrived the female assisted the couple infront of me. Gave poor service and issues with there order, the couple left with nothing. I was assisted and redeemed my offer on the app. The card machine had problems but they only have 1 machine the manager said. They reboot the system and tried again. Still the same they continued to assist other customers and just left me standing. The service is terrible, the manager can not handle pressure, screaming at staff to be patient, but we as customers are unhappy.
